DRY CLOSET.

Specicaton of Letters Patent.

Patented Aug. 20, 198.

Application filed October 22, 1917. Serial No. 197,867.

To all whom t may concern:

Be it known that I, FRANK PAvLiK, J r., a citizen of the United States, `residing at Westminster', in the county of Adams and State of Colorado, have invented certain new and useful Improvements in Dry Closets; and T do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in dry closets of the indoor chemical type, as detachably associated with a suitably connected vent conduit.

The unsanitary and inconvenient features of ont-door privies being manifest, the indoor chemical type of closet is more particularly adapted for use on the farm, home-- stead, or other outlying localities, where the installation of the usual water {iushing closets is not feasible, owing to lack of water and sewerage systems.

The general aims and functioning of these indoor chemical closets being well understood, it is believed that the utility, ob-

jects and advantages of my present invention will be clearly apparent, from the following description, and for the sake of brevity, in avoidance of unnecessary restatement, the same will not be further initially referred to.

Thus generally stated, the invention consists of the combination and structural arrangement of parts as hereinafter described, the essential features of novelty being more succinctly set forth in the appended claims; but to more clearly understand the same, reference will now be had to the accompanying drawings, forming a part of this application, in which drawings like reference characters designate the same parts in the several views, of which latter- Figure 1, is a vertical sectional view, taken along the plane of the line l-1 of Fig. 2, and showing the detachable closet and its coupled connections with its vent pipe.

Fig. 2, is a view taken sectionally through the vent pipe, on the line 2 2 of Fig. 1, being a plan of the closet cover and connections with the vent pipe.

Fig. 3, is a vertical sectional view, through the cover of the container and its connections, taken o-n the line l-l of Fig. 2, but with the coupling parts not completely housed in adjusted alining positions, and

Fig. 4f, is a fragmentary vertical sectional view, showing the same form of connections, or couplings, as in Figs. `l to 3, but disposed in a slightly different arrangement.

Referring first to Figs. l to 3, a vent pipe l leads to the atmosphere in any suitable manner, and is rigidly secured near its bottom to a side wall or suitable support by clamping means indicated at 2. Similar clamping means may be provided farther up the pipe if desired.

The lower end of this vent pipe is posi-y tioned substantially above the floor, at a distance dependent upon the height of the container and its seat.

The lower end of the vent pipe is suitably hanged, for an especial manner of seating same, the forward flange portion 3 provid# ing a flat substantial extension plate coperating with the remaining flanged portion as an element of a sliding coupling, the said flanged portions having integrally joined therewith the vertical wedge-shaped side walls 4, providing an open or trough-like wedge-shaped male coupling element, the apex of which extends forwardly of the vent pipe.

5 is a suitably constructed container or receptacle, which may have an upper lateral rearwardly projecting portion 6, shown in exaggerated dimensions, in Fig. l, for more clearly illustrating the coupling elements without crowding the drawings. This container is provided with the usual bail 7.

On the top of the container is detachably mounted the usual apertured seat 8, with its closing hinged cover, its shape being dependent upon the contour of the open top of the container.

ln the drawings this seat is shown as being rabbeted, as at 9, around its underneath peripheral edge, to detachably but snugly fit the top of the container, against displacement, and it may also be provided with a rearward separate extension 10, to which the forward portion, or seat proper, 1s hinged as at 11; f

This extension 10 is apertured at 12 to provide for free communication with the open lower end 13 of the vent pipe, when the parts are brought into alinement, and on top thereof is fixedly secured a flat metallic base plate 14, having a similarly registering opening15.

This base plate 14 is provided with wedge-shaped vertically disposed side walls 16, inturned for a short distance, as at 17, to provide a substantially open or trougl1- like wedge-shaped receiving, or female coupling element, the inturned portions 17 of which are adapted to be engaged, on their underneath faces, by the top edges o'f the wedge-shaped side walls of the male coupling element, with the side walls and bottoms of both elements disposed in relatively sliding relation, as the coupling is made or disconnected, the apex of this female coupling element being disposed forwardly, and the dimensions of the coupling element being such as to snugly contain and seat the male element carried by the lower end of the vent pipe in the manner just stated.

0n the upper face of the lian ged extension S is disposed a vertical latching lug 18, which may be curved and serrated on its engaging face, to adjustably receive the swinging end of a latching clasp or loop element 19, pivoted at 2O to the base plate 14, when the coupling elements are shoved home.

Referring now to Fig. 4, as the several elements thereof are substantially identical with those heretofore described, excepting as to disposition, they will be indicated by the same reference numerals to avoid the prolixity of restatement.

rllhe only difference in this arrangement is one of location of the element-s, owing to which it is manifest that the container 5 and the seat 8 are devoid of the extensions 6 and 10 respectively. Hence the opening 12 from the container is through its peripheral wall, instead of its seat extension 10, and similarly the base plate 14 is secured likewise to the container direct. Also the lower end of the vent pipe 1 is in the nature of an elbow. Otherwise the parts themselves are identical, and their operation obvious, requiring no further description.

As in similar types of closets, I also employ a suitable chemical mixture in the container, and the noxious odors and gases, not entirely thrown down or killed by the ychemical action, are carried away through the vent pipe by way of its coupling with the container.

lVhile the connections as set forth ordinarily sulice for venting purposes, it is obvious that any of the well known means of forced draft, sometimes used in ventilat` ing systems generally, might be employed.

With the foregoing complete disclosure,

it is thought that the operation will be fairly apparent, but it might be briefly stated that when the container is to be fitted up to the vent pipe, the male and female coupling members will be readily guided and adjust themselves relatively to each other, while the container is being shoved into position (see Fig. 3) finally making an air leak-proof connection, with the openings 12, 15 and 13 registering in alined position. Then by swinging the loop clasp 19 over the latching lug 18, the registering of the openings will be insured, and the trough-like coupling members held tightly together in wedged relation. For removing the container the operation is reversed, and the seat 8 may be readily lifted oif for emptying the container and flushing the same out.

In Fig. 4, the operation is substantially similar, the container beingplowered, from an elevated position, with the essential coupling elements functioning, however, in the manner first stated.

It will be understood that I do not make any broad claims to the detachable coupling up of a dry closet container to a vent pipe, but at the same time I do not limit myself to the exact details as set forth, excepting as come within the purview of the ensuing claims and a reasonable interpretation of the scope thereof, in the light of the speclication, contemplating a fair range of equivalent elements.

What I do claim as new and patentable, 1s
